Deep Isolation Nuclear, Inc. reported its first results as a public company for the quarter ended March 31, 2026, highlighting both rapid operational progress and a significantly wider loss. The company broke ground on its full-scale, non-radioactive deep borehole demonstration in Cameron, Texas, moving from R&D toward deployment of its nuclear waste disposal solution in partnership with Halliburton and the Deep Borehole Demonstration Center.
The demonstration, supported by collaborators including Westinghouse and NAC International, is intended to validate an integrated disposal system for advanced reactor and recycled fuel waste and generate data to support regulators and stakeholders. Deep Isolation also completed its ARPA-E ONWARDS program work, confirming via modeling that waste streams from advanced reactor fuel recycling are compatible with its deep borehole design and can meet or exceed long-term safety targets.
Strategically, the company was selected for ARPA-E’s SCALEUP Ready program, advancing contracting for up to $20 million in potential funding tied to the Texas demonstration and making it the first nuclear-sector participant in this initiative. Operationally, this positions Deep Isolation to accelerate commercialization of its Universal Canister System and underscores its bid to become a core enabler of the nuclear industry’s expansion, as demand grows for scalable long-term waste solutions.
Financially, first-quarter revenue declined about $73,000, or 5%, versus the prior-year period, mainly due to completion of certain Deep Isolation projects in 2025, partly offset by higher contract activity at subsidiary Freestone Environmental Services. Research and development expense rose by approximately $3.5 million, reflecting long-lead equipment orders and front-end engineering for the full-scale demonstration, while selling, general and administrative costs increased by roughly $1.8 million, or 186%, driven by public-company readiness, higher professional fees, travel, and four incremental hires including a CFO and General Counsel.
As a result, net loss widened by about $5.3 million year over year, with EBITDA at negative $5.6 million and Adjusted EBITDA at negative $1.5 million, both pressured by heavier R&D and overhead investment. Governance and leadership were reinforced through the appointment of veteran nuclear executive Ralph L. Hunter to the board, Paula Whitten-Doolin as General Counsel, Joseph Nelson as CFO, and nuclear operations specialist Matthew Sunseri to the advisory board, as the company prepares for scaled deployment and regulatory engagement.
On the capital markets front, the U.S. Securities and Exchange Commission declared Deep Isolation’s Form S-1 effective on May 8, 2026, allowing its common stock to become freely tradable and enabling broader investor access. The company is working with OTC Markets Group to list its shares on the OTCQB exchange, and it will host a conference call for investors to review the quarter and discuss its commercialization roadmap, underscoring a transition from technology development toward market-facing execution in advanced nuclear waste disposal.
